Amazon Echo is designed around your voice. It's always on—just ask for information, music, news, weather, and more. Echo begins working as soon as it hears you say the wake word, "Alexa." It's also an expertly-tuned speaker that can fill any room with immersive sound.

Echo's brain is in the cloud, running on Amazon Web Services so it continually learns and adds more functionality over time. The more you use Echo, the more it adapts to your speech patterns, vocabulary, and personal preferences.
